In occupational therapy, crafts and groups are used as therapeutic tools, but their electrophysiological effects have not been well described. This study aimed to investigate the effects of group crafting on the physiological synchrony (PS) of dyadic heartbeats and on the autonomic activity and electroencephalogram (EEG) of individuals. In this cross-sectional study, individuals' EEG and dyadic electrocardiogram (ECG) were measured during the task in a variety of conditions. The three conditions were alone, parallel, nonparallel. Autonomic activity from the subjects' ECG, PS from the dyadic ECG, and current source density from exact Low Resolution Brain Electromagnetic Tomography (eLORETA) from subjects' EEG were analyzed. Measurements from 30 healthy young adults showed that the parallel condition significantly increased subjects' parasympathetic activity and dyadic PS. Parallel condition and frontal midline theta influenced parasympathetic activity, whereas parasympathetic activity was not associated with PS. Dyadic lag value were correlated with frontal delta, beta, and gamma activity. The results suggest that crafting in parallel groups increases parasympathetic activity and PS through different mechanisms, despite the absence of direct interaction. They also explain the electrophysiological evidence for the use of crafts and groups in psychiatric occupational therapy, such as increased relaxation and PS.
在职业治疗中，手工艺和小组活动被用作治疗工具，但它们的电生理效应尚未得到很好的描述。本研究旨在探讨小组手工艺对双人心跳生理同步（PS）以及个体自主活动和脑电图（EEG）的影响。在这项横断面研究中，在各种条件下测量了个体在任务期间的 EEG 和双人心电图（ECG）。三种条件分别为单独、平行、非平行。从受试者的心电图分析自主活动，从双人 ECG 分析 PS，从受试者的 EEG 分析精确低分辨率脑电磁断层扫描（eLORETA）的电流源密度。对 30 名健康年轻成年人的测量结果表明，平行条件显著增加了受试者的副交感神经活动和双人 PS。平行条件和额中线θ影响副交感神经活动，而副交感神经活动与 PS 无关。双人滞后值与额部 delta、beta 和 gamma 活动相关。研究结果表明，尽管没有直接的相互作用，但平行小组的手工艺制作通过不同的机制增加了副交感神经活动和 PS。它们还解释了在精神病职业治疗中使用手工艺和小组的电生理证据，例如增加放松和 PS。
